"It is rude to hang up on people. I don't have to turn my phone off."
YES YOU DO YOU STUPID FUCKING BITCH!
In the cinema it's rude and annoying, on a plane it can be dangerous. Seriously, I think some people need to be taught a lesson and go a month without a mobile phone, the way some people act, they'll fucking kill themselves after an hour...
I remember coming back from holiday one time, as the plane touched down, someone's phone let off an incoming text message sound. DUMB. Is it so hard to turn off your phone on a plane? Or silence it in a cinema?
